Jeff Parks of Boxes and Arrows just posted a lot of material from the recent IDEA Conference (Chicago, 7-9 October), including a 41 slide presentation (pdf) by Aradhana Goel, the service design strategist at IDEO:

When we look through the lenses of society (how we connect), mobility (how to move) and sustainability (how we consume), we realize that the world has changed dramatically in the last couple of years. Aradhana Goel discusses connections between these emerging trends, design thinking, and service innovation.

You can also find audio files of the presentations by David Armano (vice-president of interaction design at Critical Mass), Alberto Cañas (co-founder and associate director at the Institute for Human and Machine Cognition), Chris Crawford (Storyton author and inventor), Bill DeRouchey (senior interaction designer at Ziba Design), Jason Fried (co-founder and president of 37signals), Jesse James Garrett (co-founder and president of Adaptive Path), Dave Gray (XPLANE founder and chairman), Andrew Hinton (lead information architect at Vanguard), Jason Kunesh (independent design professional), Elliott Malkin (artist and information architect), and Edwina von Gal (author and landscape architect).
